50% more protein “per grain” is a comparison I’ve heard here first. The intro of the paper claims “13% protein” but its comparison table states “10.1% protein”. In comparison, regular wheat has around 12.6% protein, while Einkorn wheat contains 19.3% protein. [1]
“In addition to essential fatty acids, Omegas 6 and 9, and amino acids not found in other common grains and minerals, it also has significant levels of glucose, making it a superfood with exceptional qualities for a healthy diet.”
* First, we need much more omega-3 and drastically less omega-6, while we get plenty of omega-9, which is not essential as our bodies can synthesize omega-9. [2] [3]
* Glucose and other sugars are one of the handful things that there’s a consensus it’s bad for our health.
* All plant foods contain all 20 amino-acids, essential and non-essential. [4] Naturally, rice does not lack an amino-acid in their comparison table.

OTOH, this could be an environmental friendly grain if cultivated in open seas on floating platforms instead of disrupting highly vulnerable shallow waters.
